Europe has plenty of gardeners and construction projects too, but I see at most one pickup truck per decade and it is always someone who definitely doesn’t need one and drives like they’re in a mad max movie. If you think all truck owners actually need one, count how many of the ones you see are carrying some load and do the math.

> If you think all truck owners actually need one, count how many of the ones you see are carrying some load and do the math. Okay, let's do the math. Suppose you need a truck once a week and it costs $100 to rent one. To rent one would then be $400/mo, which you haven't got. You could buy both a truck and a car and only use the truck once a week, but between payment and insurance then that's again several hundred a…

Nobody needs one once a week. Either you need for you job (and more than once a week), or you need it way less than that and renting becomes a viable option.

It took me 15 mins to get home 8km away just now. My colleague has a 500m shorter route and took 55mins. Cars are better?

You're supposed to do something about the traffic. Like build more housing so commutes are shorter distances.

More housing in _that_ model is more people with more cars on the road and needing parking spaces. The inevitable conclusion to such a model is cities like Houston, TX where everything is twice as far away because 50% of the city is just parking lot and another 25% just roads/intersections.

I drive completely in '1 pedal mode' which essentially lets regen do the braking for me. I maybe need to use actual brakes once every few days.

I would say something as well. The less noise from an EV changes people. They'll not look both ways when crossing a road and just walk out right in front of you.

You can take your car if its existence doesn't infringe on everyone else having a nice city where people can walk. For that to happen your convenience of being able to park anywhere close to your final destination will mostly disappear, you will have to find parking in a parking garage, walk up and down stairs (or take an elevator) to get to the street, and walk to your destination. I don't advocate for the extinctio…

The problem is this: If you try to allow a new dense development near the suburbs and make it affordable by not having minimum parking requirements, people object to it. Not because they want to live there and need somewhere to park their car, but because they don't want local housing to be more affordable or to have a bunch of young people with lower incomes move in and want to send their kids your school district.…

So, not stupid, instead only selfish. Much better.

Cars are a 20th century fix for the lack of easily available, comfortable, and fast public transportation. It's a shame the USA got stuck in the mid-20th century on that front.

Yep. Transit was invented to help move workers from massive factories into living areas. Definitely a 20-th century thing. And EVs are from the 21-st century. They are here to fix the utter inhumanity of dense cities, and eventually throw them into a dustbin of history.

EVs were invented in the 19th century

Cars clean the air because the AC filters capture particles

I clean the air because my lungs capture car particles.

Technically we all disinfect the water through our kidneys too

To those wondering about tire wear: "Despite the slightly higher levels of tire wear from EVs, brake dust was found to be more unhealthy, as brake dust is much more likely to become airborne (>40%) than tire wear is (1-5%). So EVs create a lot less of the worse thing, and a little more of the less-bad thing."

Is there an explanation why BEVs fare better than hybrids in terms of brake dust? They use the same principle, so I expected similar performances.

The article gives no clues, only these results:

> It turns out that BEVs reduce the amount of brake dust by 83% [...] Other vehicles that use regenerative braking reduced brake emissions too, with Hybrids reducing them by 10-48%, and PHEVs by 66%.

So EVs create a lot less of the worse thing, and a little more of the less-bad thing."

So putting this aside, the elephant in the room is still the weight of the EVs, tire wear is one thing but the roads are also being worn at a much faster rate due to the weight of the cars. When EVs do have to brake and regenerative is not enough it needs to stop more inertia due to this high weight.

A Tesla 3 is 5% heavier than a BMW 3. First generation ICE conversions were heavy. Cars properly designed from the ground up for EV aren't as much.
